NAME

ibv_get_pkey_index - obtain the index in the P_Key table of a P_Key  

SYNOPSIS


#include <infiniband/verbs.h>

int ibv_get_pkey_index(struct ibv_context *context,
                       uint8_t port_num,
                       __be16 pkey);
 

DESCRIPTION

Every InfiniBand HCA maintains a P_Key table for each of its ports that is indexed by an integer and with a P_Key in each element. Certain InfiniBand data structures that work with P_Keys expect a P_Key index, e.g. struct ibv_qp_attr and struct ib_mad_addr. Hence the function ibv_get_pkey_index() that accepts a P_Key in network byte order and that returns an index in the P_Key table as result.  

RETURN VALUE

ibv_get_pkey_index() returns the P_Key index on success, and -1 on error.
